I dont like the jimping on the handle of the ZT0560, when using the flipper tab. Thought it would be the same for the XM-18.
Then after picking up the Eklipse, the detent feels weak and doesn’t allow the blade to pop out. I preferred using the thumb studs.
Cool. Interesting to hear about the difference preferences folks have with gear.
Are you referring to the jimping on the blade or the frame/handle? Seems like the XM-18 has similar jimping as the ZT 0560.
I had gotten used to knives with thumb studs like the Benchmade Griptilian or similar with the axis lock. They are quick to deploy with a flick to the wrist where you rotate the handle around the pivot pin, or using the "J open" method where you make a J in the air with the pivot pin end of the handle. Some models can take some adjustment to get just right, but all of the Benchmades with axis lock that I have had were able to do so. I found through combatives training that opening via the thumbstud wasn't as dependable, at least for me. I'd miss the thumbstud or even sweaty hands made it more difficult to open. The thumbstud on the Hinderers look quite smooth.
I haven't found a good training knife with the flipper, but I like the flipper in that it seems more dependable opening (at least for me) and I also like that the flipper ends up being a hand/finger guard when open.
I still have Benchmades with thumbstud models in the carry rotation, including assisted openers. But I've been mostly sticking with the flipper openers (ZT and Boker). Like many things, I probably should stick to one of the other if primarily for defensive use.
